You have to consider a couple of items:
Do you want to use the crossover in the subwoofer or run everything full range. Right now, you could either use the line level from your pre into the sub, then to the power amp. OR you can use the speaker level outs from the crown to the sub to the speakers.
The other options are: You can use a Y cable from your pre to the amp and sub to avoid the crossover. OR you could use a sub like REL that has speaker level taps that won't interfere with the signal at all.
Personally, I would like to ask if you have tried a home audio amp vs the crown? Also, what is your pre amp? Commercial and home audio can be quite different-IN MY OPINION
